中文摘要: 采用氯化焙烧工艺从硫铁矿烧渣球团中综合回收金、银、铜等有价金属,考察了造球、窑温、停留时间对金属挥发率以及物料和金属平衡的影响。结果表明,物料在1 250 ℃停留1.83 h的最佳条件下,各金属挥发率为:Au 95.6%、Ag 52.5%、Cu 73.1%、Pb 93.9%、Zn 75.2%。球团中铜、铅、锌含量均小于0.1%,球团强度4 0~6.5 kN。
Abstract:Valuable metals such as Au, Ag, and Cu were comprehensively recovered from pyrite cinder by chloridizing roasting process. The effects of pelletizing, roasting temperature and staying duration on metal volatilization rates and mass balance of materials and metals were investigated. The results show that the volatilization rates of Au, Ag, Cu, Pb, Zn are 95.6%, 52.5%, 73.1%, 93.9%, and 75.2% respectively under the optimum conditions including roasting temperature of 1 250 ℃ and staying duration of 1.83 h. The contents of Cu, Pb, Zn in chloridizing pellet are all below 0.1%, and the compression strength of pellet is 4 0~6.5 kN.
